It’s being reported that Emily Blunt has entered into negotiations to star in Disney’s sequel to Mary Poppins, taking on the title role played by Julie Andrews in the 1964 classic.

Though Blunt is in talks for the role, and is said to have always been the top choice to take on the iconic character, it’s not yet certain she’ll be able to take the job. The actress is currently expecting her second child, and there’s a chance that that could prevent her from being able to commit to the project.
